if that header file isn't used by any kernel code, why bother having a
check for __KERNEL__ in the first place?  it's being exported to
userspace unchecked:

  include/linux/Kbuild:header-y += hdsmart.h

so why not just toss that check entirely?  otherwise, you're going to
get a header file exported to userspace that has a superfluous
__KERNEL__ test in it.
